There’s a Formula Linking V and I Flashcards
1
Q
What is the formula relating resistance, voltage and current?
A
Voltage = current x resistance
2
Q
What does the gradient of an I-V graph show you?
A
How the resistance of the component behaves
3
Q
The steeper the graph…
A
The lower the resistance
4
Q
What does it mean if a graph curves?
A
It means the resistance is changing
5
Q
What does a straight-line graph have?
A
A constant gradient and shows a constant resistance
